Description

Technical Field

[0001] This invention relates to the field of turbochargers, and more particularly to a turbocharger with a foreign matter rejection function. Background Technology

[0002] A turbocharger is an air compressor that increases the output power of an engine. The principle of a turbocharger is that the engine generates and discharges exhaust gas. After the exhaust gas enters the exhaust pipe, it drives the fan blades inside the exhaust pipe to rotate, which in turn drives the coaxial impeller to rotate, thereby increasing the intake pressure and the engine's output power.

[0003] Patent publication number CN216240835U discloses a turbocharger volute and a turbocharger, including a turbocharger volute, a vortex flow channel, and a first tapering flow channel. The turbocharger volute is provided with a vortex flow channel for collecting engine exhaust gas. The vortex flow channel includes a first tapering flow channel, a second tapering flow channel, and a third tapering flow channel arranged sequentially and connected along the airflow direction. The first tapering flow channel extends from the 0° section of the volute flow channel and ends at the 60° section of the volute flow channel. The second tapering flow channel extends from the 60° section of the volute flow channel and ends at the 300° section of the volute flow channel.

[0004] The aforementioned turbocharger volute and turbocharger increase intake pressure and improve turbocharger efficiency by collecting engine exhaust gas and driving the impeller to rotate by airflow. However, during maintenance, foreign objects can easily enter the flow channel of the turbocharger volute and turbocharger, which can easily lead to damage to the internal components of the turbocharger. Now, a turbocharger with foreign object removal function is being developed. Summary of the Invention

[0005] In order to overcome the shortcomings of existing turbocharger casings and the ease with which foreign objects can enter the turbocharger, the technical problem of the present invention is to provide a turbocharger with a foreign object removal function.

[0006] The technical solution of the present invention is as follows: a turbocharger with a rejection function, comprising a turbocharger body, a connecting cavity, a door, a torsion spring, a blocking mechanism and a rejection mechanism. The front part of the turbocharger body is connected to the connecting cavity, and the lower left and right sides of the connecting cavity are rotatably connected to doors. The front and rear sides of the side of the doors that are close to each other and the connecting cavity are all wound with torsion springs. The connecting cavity is provided with a blocking mechanism, and rejection mechanisms are provided on the left and right sides of the blocking mechanism.

[0007] Furthermore, the blocking mechanism includes a first cylinder, a connecting plate, and a blocking plate. The first cylinder is located on the right side of the inside of the connecting cavity. The left side of the telescopic rod of the first cylinder is connected to the connecting plate. The connecting plate and the connecting cavity are slidably connected. Two blocking plates are connected to the rear of the connecting plate.

[0008] Furthermore, the exclusion mechanism includes a curved plate, a lower pressure rod, and a first compression spring. Curved plates are connected to both the left and right sides of the connecting plate. Lower pressure rods are slidably connected to both the left and right sides inside the connecting cavity. The lower pressure rods are pressed and engaged with the adjacent curved plates and the adjacent door. The upper part of the lower pressure rod and the connecting cavity are both wound with the first compression spring.

[0009] Furthermore, it also includes a push-out mechanism for pushing out foreign objects attached to the baffle plate. The push-out mechanism includes a second cylinder, a connector and a push plate. The second cylinder is connected to the rear left part of the connecting cavity. The connector is connected to the telescopic rod of the second cylinder. The push plate is connected to the right part of the connector. The push plate and the baffle plate are slidably connected.

[0010] Furthermore, it also includes a scraping mechanism for further cleaning the baffle plate. The scraping mechanism includes a wedge, a scraper and a tension spring. The scraper is slidably connected to the upper part of the connecting cavity. The wedge is connected to the rear part of the scraper. The wedge and the connecting cavity are slidably connected. The wedge and the connector are pressed together. A tension spring is wound between the upper front part of the scraper and the connecting cavity.

[0011] Furthermore, it also includes a vibration mechanism for striking the connecting cavity to promote the discharge of foreign objects from the connecting cavity. The vibration mechanism includes a protrusion, a vibration rod, a slide rail, and a second compression spring. The lower part of the pressure rod is connected to a protrusion, and the left and right sides of the lower rear part of the connecting cavity are connected to slide rails. Vibration rods are slidably connected to the slide rails. The vibration rods are all in a pressing fit with the connecting cavity and the protrusions. The rear part of the vibration rod and the adjacent slide rail are all connected to a second compression spring.

[0012] Furthermore, it also includes a filter screen for preventing foreign objects from entering the turbocharger body, with the filter screen connected to the left side of the turbocharger body.

[0013] Furthermore, the number of bumps is three.

[0014] The beneficial effects are: 1. By setting up a blocking mechanism and a discharge mechanism, the present invention blocks foreign objects from entering the turbocharger body through the blocking plate, and drives the curved plate to move through the connecting plate, so that the lower pressure rod is squeezed downward by the curved plate, and the lower pressure rod squeezes the door open downward, so that the foreign objects can be discharged from the connecting cavity.

[0015] 2. By setting up a push-out mechanism, the push plate moves forward and inserts into the blocking plate, thereby allowing foreign objects attached to the blocking plate to be pushed forward, which facilitates the subsequent blocking of foreign objects by the blocking plate and helps the turbocharger with foreign object removal function to block and remove foreign objects.

[0016] 3. By setting up a scraping mechanism, the inclined block is released by the forward movement of the connecting piece, so that the scraper moves downward under the action of the tension spring to scrape off the foreign objects attached to the baffle plate, further cleaning the baffle plate and making it easier for the baffle plate to block foreign objects in the future. This helps the turbocharger with foreign object removal function to block and remove foreign objects.

[0017] 4. The present invention sets up a vibration mechanism. The downward movement of the pressure rod drives the protrusion to press the vibration rod backward, so that the vibration rod can move forward and reset under the action of the second compression spring and knock on the connecting cavity. The connecting cavity vibrates, thereby further promoting the discharge of foreign objects.

[0018] 5. This invention uses a filter screen to isolate foreign objects from the turbocharger body, preventing them from entering. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] A turbocharger with rejection function, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a turbocharger body 1, a connecting cavity 2, a door 21, a torsion spring 22, a blocking mechanism 3, and a discharge mechanism 4. The front of the turbocharger body 1 is connected to the connecting cavity 2. The lower left and right sides of the connecting cavity 2 are rotatably connected to the door 21. The front and rear sides of the door 21 that are close to each other are wound with the connecting cavity 2. The connecting cavity 2 is provided with a blocking mechanism 3. The blocking mechanism 3 is used to block foreign objects from entering the turbocharger body 1 and push the foreign objects to help them exit the connecting cavity 2. The left and right sides of the blocking mechanism 3 are provided with discharge mechanisms 4. The discharge mechanisms 4 are used to allow foreign objects to exit the connecting cavity 2.

[0034] like Figure 2 and Figure 5 As shown, the blocking mechanism 3 includes a first cylinder 31, a connecting plate 32, and a blocking plate 33. The first cylinder 31 is located on the right side of the inside of the connecting cavity 2. The left side of the telescopic rod of the first cylinder 31 is connected to the connecting plate 32. The connecting plate 32 and the first cylinder 31 are used to push foreign objects to help them exit the connecting cavity 2. The connecting plate 32 and the connecting cavity 2 are slidably connected. Two blocking plates 33 are connected to the rear of the connecting plate 32. The blocking plates 33 are used to block foreign objects from entering the turbocharger body 1.

[0035] like Figure 2 and Figure 6As shown, the removal mechanism 4 includes a curved plate 41, a pressing rod 42, and a first compression spring 43. The curved plates 41 are connected to both the left and right sides of the connecting plate 32. The pressing rods 42 are slidably connected to both the left and right sides of the interior of the connecting cavity 2. The pressing rods 42 are pressed and engaged with the adjacent curved plates 41 and the adjacent door 21. The first compression spring 43 is wound around the upper part of the pressing rod 42 and the connecting cavity 2. The curved plates 41 are moved by the connecting plate 32, so that the pressing rod 42 is pressed downward by the curved plates 41. The pressing rod 42 presses the door 21 open downward, so that the foreign object can be discharged from the connecting cavity 2.

[0036] When using this turbocharger with foreign object rejection function, the turbocharger body 1 and connecting cavity 2 need to be installed on the car and used normally. When a foreign object enters the connecting cavity 2, the baffle plate 33 will block the foreign object, preventing it from entering the turbocharger body 1. During subsequent maintenance of the car, the first cylinder 31 is started. Driven by the extension rod of the first cylinder 31, the connecting plate 32 moves to the left. The foreign object is pushed to the left by the connecting plate 32 and falls to the upper part of the left door 21. The connecting plate 32 drives the baffle plate 33. Both the curved plate 3 and the curved plate 41 move to the left. During this movement, the left curved plate 41 contacts the left-side pressing rod 42, and the right curved plate 41 contacts the right-side pressing rod 42. At this moment, the left curved plate 41 presses down on the left-side pressing rod 42, and the right curved plate 41 presses down on the right-side pressing rod 42, causing both pressing rods 42 to move downwards. The first compression spring 43 is compressed, and the left pressing rod 42 presses down on the left-side door 21, causing the left side... Door 21 rotates counterclockwise to open, and the right-side pressing rod 42 presses down on the right-side door 21, causing the right-side door 21 to rotate clockwise to open. The torsion springs 22 all twist, allowing foreign objects to be discharged from the gap between the left-side door 21 and the connecting cavity 2. Then, driven by the telescopic rod of the first cylinder 31, the connecting plate 32 moves to the right to reset. The connecting plate 32 drives the curved plate 41 to move to the right to reset. When the curved plate 41 is no longer in contact with the pressing rod 42, the pressing rod 42 moves upward under the action of the first compression spring 43. Reset. At this time, the left door 21 closes clockwise under the action of the torsion spring 22, and the right door 21 closes counterclockwise under the action of the torsion spring 22, closing the first cylinder 31. When using the car, the baffle plate 33 prevents foreign objects from entering the turbocharger body 1. When it is necessary to discharge foreign objects, the connecting plate 32 drives the curved plate 41 to move, so that the lower pressure rod 42 is pressed down by the curved plate 41. The lower pressure rod 42 presses down and opens the door 21, so that foreign objects can be discharged from the connecting cavity 2.

[0037] Example 2

[0038] Based on Example 1, such as Figure 2 and Figure 7As shown, it also includes a push-out mechanism 5, which includes a second cylinder 51, a connector 52 and a push plate 53. The second cylinder 51 is connected to the rear left part of the connecting cavity 2. The connector 52 is connected to the telescopic rod of the second cylinder 51. The push plate 53 is connected to the right part of the connector 52. The push plate 53 is used to push the foreign objects attached to the baffle plate 33 forward. The push plate 53 and the baffle plate 33 are slidably connected.

[0039] like Figure 2 and Figure 8 As shown, it also includes a scraping mechanism 6, which includes a wedge block 61, a scraper 62, and a tension spring 63. The scraper 62 is slidably connected to the upper part of the connecting cavity 2, and the wedge block 61 is connected to the rear part of the scraper 62. The wedge block 61 and the connecting cavity 2 are slidably connected. The wedge block 61 and the connector 52 are pressed together. The tension spring 63 is wound between the upper front part of the scraper 62 and the connecting cavity 2. The wedge block 61 is released by the forward movement of the connector 52, so that the scraper 62 moves downward under the action of the tension spring 63 to scrape the foreign objects attached to the baffle plate 33, further cleaning the baffle plate 33 and facilitating the subsequent blocking of foreign objects by the baffle plate 33.

[0040] like Figure 1 , Figure 3 , Figure 9 and Figure 10 As shown, it also includes a vibration mechanism 7, which includes a protrusion 71, a vibration rod 72, a slide rail 73, and a second compression spring 74. The lower part of the pressing rod 42 is connected to three protrusions 71. The left and right sides of the lower rear part of the connecting cavity 2 are connected to slide rails 73. The vibration rod 72 is slidably connected to the slide rail 73. The vibration rod 72 is pressed and engaged with the connecting cavity 2 and the protrusion 71. The rear part of the vibration rod 72 and the adjacent slide rail 73 are connected to the second compression spring 74. When the pressing rod 42 moves downward, it drives the protrusion 71 to press the vibration rod 72 backward, so that the vibration rod 72 can move forward and reset under the action of the second compression spring 74 and knock on the connecting cavity 2. The connecting cavity 2 vibrates, thereby further promoting the discharge of foreign objects.

[0041] like Figure 3 and Figure 11 As shown, it also includes a filter screen 8. The left side of the turbocharger body 1 is connected to the filter screen 8. The filter screen 8 is used to isolate foreign objects from the outside, so that foreign objects cannot enter the turbocharger body 1.

[0042] Before expelling foreign objects, the second cylinder 51 is activated. Driven by the extension rod of the second cylinder 51, the connecting piece 52 moves forward, and the connecting piece 52 drives the push plate 53 to move forward, so that the push plate 53 is inserted into the baffle plate 33, pushing out the foreign objects attached to the baffle plate 33. Then, driven by the extension rod of the second cylinder 51, the connecting piece 52 drives the push plate 53 to move backward and reset, and the second cylinder 51 is closed. By moving the push plate 53 forward and inserting it into the baffle plate 33, the foreign objects attached to the baffle plate 33 can be pushed forward, which facilitates the baffle plate 33 to block foreign objects in the future, and helps the turbocharger with foreign object removal function to block and remove foreign objects.

[0043] The initial state of the inclined block 61 is that it is squeezed by the connector 52. At this time, the tension spring 63 is stretched, and the scraper 62 is located above the baffle plate 33. When the connector 52 drives the push plate 53 to move forward and insert into the baffle plate 33, the inclined block 61 does not contact the connector 52 as the connector 52 moves forward, and the inclined block 61 is released. Under the action of the tension spring 63, the scraper 62 moves downward, and the inclined block 61 moves downward. At this time, the scraper 62 scrapes off the foreign matter attached to the baffle plate 33. When the connector 52 drives the push plate 53 to move backward and reset, the connector 52 squeezes the inclined block 61 upward, so that the inclined block 61 drives the scraper 62 to move upward and reset together. At this time, the tension spring 63 is stretched again, and the inclined block 61 is released by the forward movement of the connector 52. Under the action of the tension spring 63, the scraper 62 moves downward to scrape off the foreign matter attached to the baffle plate 33, further cleaning the baffle plate 33, which facilitates the subsequent blocking of foreign matter by the baffle plate 33, and helps the turbocharger with the foreign matter removal function to block and remove foreign matter.

[0044] To further promote the removal of foreign objects, when the pressing rod 42 moves downward, the protrusion 71 moves downward under the action of the pressing rod 42. When the protrusion 71 contacts the vibrating rod 72, the vibrating rod 72 moves backward under the pressure of the protrusion 71, and the second compression spring 74 is compressed. When the protrusion 71 is no longer in contact with the vibrating rod 72, the vibrating rod 72 moves forward to reset under the action of the second compression spring 74 and strikes the connecting cavity 2. Because there are three protrusions 71, the vibrating rod 72 can strike the connecting cavity 2 three times during the downward movement of the pressing rod 42. This not only promotes the removal of foreign objects from the connecting cavity 2, but also allows the foreign objects attached to the inner wall of the connecting cavity 2 to be completely shaken off by the multiple strikes. The downward movement of the pressing rod 42 causes the protrusion 71 to press the vibrating rod 72 backward, which allows the vibrating rod 72 to move forward to reset under the action of the second compression spring 74 and strike the connecting cavity 2. The connecting cavity 2 vibrates, thereby further promoting the removal of foreign objects.

[0045] To prevent foreign objects from directly entering the turbocharger body 1 from the outside, a filter screen 8 is used to isolate foreign objects, preventing them from entering the turbocharger body 1.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
